Question

我正在创建一个使用Firebase通知的应用程序，除了用户点击通知，我想打开一个活动以及当用户点击后退按钮时，我希望返回主页活动，但现在应用仅在用户点击后退按钮时关闭。

这是我的清单代码：

@Autowired
private VelocityEngine velocityEngine;

public String prepareRegistrationEmailText(User user) {
    VelocityContext context = new VelocityContext();
    context.put("username", user.getUsername());
    context.put("email", user.getEmail());
    StringWriter stringWriter = new StringWriter();
    velocityEngine.mergeTemplate("registration.vm", "UTF-8", context, stringWriter);
    String text = stringWriter.toString();
    return text;
}

和我发送通知的php脚本：

    <?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.example.massa.luxvilla">



    <uses-permission android:name="android.permission.INTERNET" />

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

    <uses-permission android:name="android.permission.VIBRATE" />



    <application

        android:allowBackup="true"

            </intent-filter>



            <meta-data

                android:name="android.app.searchable"

                android:resource="@xml/searchable" />

        </activity>

        <activity

您可以在通过通知打开的Activity中尝试这样的事情：

@Override
public void onBackPressed() {
    if (isTaskRoot()) {
        finish();
        startActivity(new Intent(this, MainActivity.class));
    } else {
        super.onBackPressed();
    }
}

如果任何Activity在同一任务的堆栈中，您将检查，如果没有，您将打开MainActivity

Firebase通知单击操作活动父活动
